Kvyat, who returned to F1 this year with the Honda Toro Rosso, drove his lap with the fastest available tire, two steps less than Vettel's – and it's unclear what fuel loads each team will use.

"That was not the priority [being fastest]"The priority was to get back on my feet after the first day, which was not ideal," Kvyat said. "But we recovered enough and more, that's great, a productive day."

Williams finally entered the F1 2019 season on Wednesday after missing the opening two days while Mercedes continued to hold their cards close to the chest.

Valtteri Bottas and Lewis Hamilton were next to Williams' George Russell the slowest riders on the track. They finished eleventh and twelve, three seconds behind Kvyat's main time.

However, the World Champions completed the most laps with a total of 182 laps and said they focused on maximizing laps and editing our program.

Glory is in full swing, Williams returnsKvyat set his benchmark in the final 15 minutes of the day, when many of the fastest test rounds were set.

Many of the teams seem to send their drivers to "glory rides" at this time, presumably with less fuel.

For example, Kvyat had completed well over a century of laps before riding a second faster than his previous personal best.

Räikkönen was in the lead for most of the day for Alfa Romeo, the former Sauber team, who was a seasoned backer before improving last season. The Swiss outfit was one of the most important stories in the test with its innovative and fast C38.

Ferrari was the fastest in Barcelona in the past two days, but ended his program with a half-hour remaining on Wednesday. Vettel was two tenths slower from his first day than his personal best, and Charles Leclerc will return to SF90 on the last day of the first day of testing on Thursday.

Max Verstappen was fifth when Red Bull finally revealed his speed with the Honda engine, while Nico Hülkenberg also dipped for Renault in the 1:18 time.

Haas was plagued by more reliability issues, leading to multiple red flags after Pietro Fittipaldi and Romain Grosjean had stopped on the track.

And McLaren could not improve the pace of the previous two days when Carlos Sainz finished ninth in front of Sergio Perez and the two Mercedes drivers.

But Hamilton seemed content with his W10 when he hit the media earlier in the day

Williams was at rock bottom with Russell, but the Grove team will be relieved after the catastrophic start to the season.

Russell completed 23 laps, which was essentially a shakedown for the team, which only put its FW42 on the track in the early hours of the morning.

Team Principal Claire Williams, who has spoken openly with Sky F1 about her "terrible" delay, says the aerodynamic tests will start on Thursday as the team begins to learn where they stand in this intriguing pecking order.
